material mechanical properties

all of the following describe force except

• produces movement to a body at rest
• produces Acceleration of a moving body
• deforms the body if its constrained
• none of the above

the measuring unit for force is

• newton
• pascal
• Fahrenheit
• all of the above

which of the following has the highest mastication force

• 6 year old girl
• 26 year old male
• 30 year old female
• 11 year old boy

which of the following teeth can withstand the most force

• upper central
• lower lateral incisor
• upper canine
• lower first molar

It is internal reaction of the constrained body to external applied force equal in magnitude and in opposite direction

if you know that the simple version of newton 3rd law is that every action has a reaction opposite in direction with the same magnitude this is similar to

• stress
• force
• strain
• none of the above

the measuring unit for strain is

• newton
• pascal
• tesla
• none of the above

the measuring unit for stress is

• newton
• cubic meters
• tesla
• pascal

which of the following is true about compression stress

• composed of 2 sets of axial forces acting away from each other
• composed of 2 sets of parallel forces acting towards each other
• makes the object shorter
• the two forces slide upon each other

this graph describes the relation between

• stress and area
• density and volume
• thermal diffusivity and specific heat
• stress and force
